Some people may think that cucumbers and zucchini are the same, but actually, they are different. Zucchinis are known to be warm, usually when you hold them. They will start to feel a bit gritty when you touch them. With cucumbers, they are known to be hard and waxy. If you held them, they would be a bit cool. This is how the saying “cool as a cucumber” started. Another thing that you should look at is their exterior.
You may notice that most cucumber types will have a bumpy exterior. There are some that may have smoother exteriors, though. Zucchinis tend to be smoother. In terms of taste, Zucchini may come with a more bitter flavor as compared to the cucumber.
